"Glad to check why you can't complete any of your recent purchases.
「很高兴为您服务，解答您不能完成任何支付的问题。
Looking at your account, I can see that you are attempting to use a payment method registered outside your current region.
查看您账户信息后我们发现您使用的支付方式与当前设置的地区不符。
Purchases made through Steam must be made in the region you are physically located and using a payment method associated with a local address.
在Steam上购买时请注意您的物理所在地必须符合所设置的地区，任何支付方式也必须和当地地址所关联。
Please try an alternate payment method. You can also look for Steam-compatible CD Keys and/or Steam Wallet Codes at your local gaming retail stores.
请尝试不同的支付选项，或使用序列号等激活方式添加游戏。
Feel free to reach out if you need help with anything else.
如有其他疑惑，欢迎回复。
